PIETER HONDIUS, or UTREOHT, NETHERLANDS.

PROCESS OF IMPREGNATI'NG TOBACCO BY MEANS OF NATURALOR ARTIFICIALAROMATIC SUBSTANCES.

' the Netherlands, residing at Utrecht, Buys Ballotstraat 5* in theKingdom of the Netherlands, have invented certain new and usefulImprovements in Processes for the Impregnation of Tobacco byMeans ofNatural or Artificial Aromatic Substances or Organic Salts, of which thefollowing is a full, clear, and exact description.

The quality and value of tobaccos depend upon their certain materials,which influence the burning of the tobacco and the color of the ash.

I have found that the value of tobacco leaves can be favorablyinfluenced by their impregnation with substances which are contained insuperior kinds of tobacco and the quality of inferior tobaccos can inthis way therefore be raised to a higher value.

This invention consists in the method of improving the burning qualityand flavor of badly burning cigars by impregnating parts thereof with anextract of tobacco of good burning quality and of a flavor superior tothat of the cigars treated.

In practice the following is the process used :Waste cuttings of theleaves, stalks,

and ribs, or other residues of the tobacco factory, of good burningtobacco and tobaccos rich in organic salts, such as Deli-Langkat,Sumatra, or the like, are used, and are soaked in water and the solutionor extract obtained is concentrated by boiling, so that about a 10 percent solution is obtained. The 10 per cent extract thus obtained thenserves for the impregnation of inferior-burning kinds of tobacco, suchfor example as Rio Grande, Java, Telock, Java, S. K., Deli and Slamat,Borneo. These last named kinds of tobacco are those which are preferablyto be treated according to the new process, but other kinds of tobaccoof inferior burning quality can be very greatly improved by the use ofthe extract obtained in the way, and from the superior tobaccos abovedescribed. This improvement is effected by treating the inferior kindsof tobacco named, for a certain time, for example, 24 hours, with a tenper cent solution of the extract which is prepared from good burningtobacco, as already mentioned.

effect the neutralization of the nicotin, as

this is present especially in the inner part of or filling and anyattempted improvement in the quality of the cigars themselves which maybe made according to the processes heretofore employed, is not all aimedat in the present invention, in which the good-burning of the envelop orwrapping an outer covering is alone aimed at and effected. To improve inthis way the burning of the cigar it is necessary, according to theprocess of the present invention to prepare an aqueous extract of themore or less waste parts of good-burning and more valuable kinds oftobacco, suchfor example as Deli-Langkat, Sumatra, and 1 solutioncontaining for example, about 10 per cent of the material thus extractedfor a determined time, about 24 hours.

The most successful method for the preparation of the extract is carriedout as follows :--An extract is made from cuttings of the leaves orother suitable parts of good burning tobacco, by means of water, andthis extract is then concentrated vby heat, the injurious inflammablesubstances such as albumen and the like being removed by drawing themoff, skimming or filtering and the so-prepared extract is thickened byevaporation in vacuo until a viscous dark brown syrup containingcrystals is obtained. By further inspissation a more or less solidgreyish-white mass results, which like the syrup is easy to transportfrom place quired.

When required for use a suitable quantity of thesyrup or product of thekind described is thinned downwith water and the kinds of inferiorburning tobacco to be treated are impregnated with it for a sufficientlylong time, quality and of a flavor superior to that of the IO orinstance, for one day. cigars treated.
